A former female jailer at the Effingham County Jail alleged to have had improper contact with an inmate was arrested by sheriff’s investigators Tuesday afternoon.

Jessica Edenfield, 29, of Guyton, has been charged with one count of sexual assault against a person in custody. She was fired as a jailer last month during the investigation of the incident.

Edenfield posted bond and was released.

Sheriff’s officials say that their investigation revealed Edenfield was having sexual relations with a male jail inmate.

“We will not tolerate any behavior which is not in accordance with our professional standards,” Sheriff Jimmy McDuffie said in a prepared statement. “Any employee at this office found to be in violation of Georgia law will be prosecuted to the fullest extent of the law.”

According to reports, Edenfield and the inmate had sexual contact in the control room, where the inmate was not allowed. McDuffie said he believed the two may have had only one instance of such contact and that they did not know each other prior to their incident.

The sheriff also said his department will make changes in its procedures to ensure there are enough jail personnel in certain areas.

McDuffie said Edenfield admitted to investigators she had improper conduct with an inmate.

“We had information on it, and they followed up on it,” he said.
